If you're going to add categories to a page, you'd best add them all at once. If you add them one by one like you're doing now, it just crams up the wiki activity and is outright spam. So please add categories properly.
Oh and, stop removing that plagiarism template. It's incredibly easy to figure out if information on a particular page on this wiki is plagiarized via Google searching the info, and I can easily tell the majority of the information on that page you made was plagiarized. There's no hiding it. Keep up your behaviour and you WILL be reproted to an admin.
It is. Look at the History paragraph for example. I can tell that you've copied all of it straight from the Negima Wiki. That's what the Wiki's definition of plagiarism is. The abilities section is also copied from the Wiki. As far as I can tell, I don't see how it isn't plagiarism, since you have lied about having so-called "permission" to copy all of that information and yet you have provided no proof at all and have not made a single edit on the Negima Wiki.
